语言包的问题：缺少列名称

时间：2017-06-15 07:16:19

标签： internationalization jasper-reports

我有一份报告，我正在尝试测试本地化

因此，我将3个语言文件存在于已配置为源路径的文件夹中

现在，报告中的表格有四列。国家，州，名称和年龄。存在3个语言文件language_en_US，langauage_fr_FR，language_pt_PT。根据相应的语言，每个列中的每个列的名称都存在。我已使用$R{}

配置表格列标题的文本表达式
  1. 但是，当我运行报表时，所有列标题的名称都为null。为什么会这样？
  2. 如何在运行时选择不同的语言？报告总是运行en_US，这是默认值？我确实想使用report_locale参数
  3. 我可以使用其他参数，将其值设置为所需的区域设置，然后将此区域设置传递给捆绑包吗？

    4. 请在下面找到jrxml

    对此有何帮助？

1 个答案:

答案 0 :(得分：0)

我确实想到了这一点。我不得不将$ R {languages.country}改为$ R {country}。并将resourceBundle =“languages / languages”更改为resourceBundle =“languages”

由于 瑞斯
